What type of material is the handle?

Each kennel door comes with a strong, lockable stainless steel handle. Inside the handle is a stainless steel spring that helps keep the latch closed, so your dog can’t push the door open. It’s safe and secure, but still easy to open with one hand. You can also add a padlock or clasp for extra security if needed.

Are these kennels easy to assemble?

Your kennel ships with easy assembly instructions, covering all essential components:

  • Kennel panel setup
  • Panel-to-panel coupling
  • Handle & quick-lock latch installation
  • Top mesh panels (if applicable)
  • Isolation panels (if applicable)
  • Back-to-back panel configurations

Do these runs meet commercial kennel standards?

Yes, TK Products kennels are built to meet commercial kennel standards. They’re designed with high-quality materials and durable construction to ensure long-lasting performance, safety, and ease of maintenance—making them ideal for professional boarding facilities, breeders, shelters, and veterinary clinics.

Can I anchor them to concrete or grass?

Yes! TK Products kennels can be securely anchored to both concrete and grass. We offer anchoring kits designed for different surfaces to ensure your kennel stays stable and secure in any setup.

How long is your warranty?

All TK Products kennels include an industry-leading 5-year warranty—far exceeding what most competitors offer in the kennel market.
